3 Claims. 1

This invention relates to packaging devices or receptacles with closures for use in attractively marketing products and providing a handy container for storing the product to make the same repeatedly available for use. More particularly the, invention is directed to an improvement in container having a readily removable closure of novel construction and to such closures and new articles of manufacture for use as cap-stopper closures.

Among the objects of the invention is to generally improve devices of the character described which shall comp-rise few and simple parts that are readily assembled to form attractive packaging receptacles that can serve as a container to permitrepeated removal and replacement of the contents or to form cap-stopper closures of novel construction, which shall be cheap to manufacture and capable of being made in quan tity production, which shall be easy to keep in a clean sanitary and hygienic condition when employedas a container for repeated use, and which shall be practical and efiicient to a high degree.

Other objects of the invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists of features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter disclosed, the scope of the application of which will be indicated in the claims following.

In the accompanying drawing in which one embodiment of the invention is shown,

Fig. 1 is a front elevational view of a packaging device constructed toembody the invention in the form of an improved receptacle having a novel closure construction suitable for marketing toothbrushes and the like in an attractive form and providing a handy container or holder for the toothbrush with a handy removable closure for repeated use shown in closed position and partly broken away to expose the contents.

Fig. 2 is an enlarged top plan view of the improved'device shown in Fig. 1.

Fig. 3 is an enlarged fragmentary cross-sectional view taken on line 33 in Fig. 2 showing details of the improved cap-stopper closure.

Fig- 4 is a fragmentary cross-sectional View of the container capped portion corresponding to a section taken on line i -4 in Fig. 3.

Fig. 5 is an enlarged fragmentary view similar to Fig. 3 showing the improved cap-stopper in an open position, and

Fig. 6 is an enlarged plan view'of the device as seen from-linefi6 in Fig. 5.

Referring in detailto the drawing l0 denotes a packaging device or receptacle adapted to be used for attractively marketing a product, and also providing a handy container for making repeatedly available the contents, as here shown, the product being a toothbrush B, said packaging device and a cap-stopper closure l l thereof bein constructed to embody the invention.

As seen from Fig. 1, device [0, may comprise a container I2 which for the purpose of marketing a contained article, such as toothbrush B, may be made of clear transparent, colored transluscent or colored opaque tubular body 112a closed at one end 1222 and open at the other end I20. The latter may be provided with an. exterior extended rim edge bead [2d, said container 12 being shaped and sized to conform to the dimen-'- sions of the contents, here shown to accommodate toothbrush B. As shown in Fig. 6 .saidcontainer I2 may be'of oval-like sectional shape to permit the toothbrush B to be freely inserted and removed, from the container I2yet neatly fitted therein as indicated in Fig. 1. Container [-2 may .be, if desired, molded of a suitable plastic material having so-called shatterproof properties.

loothbrush B is confined in said container 12 by cap-stopper closure ll of improved construc: tion and may be made of a molded resilient material, for example, rubber or a suitable plastic, such as polyethylene.

Cap-stopper closure II when molded may be initially formed as a single piece stretched out, structure corresponding to that shown in Figs. 5 and 6, and is seen tov comprise an expandable annular band portion Ila having a resilient clamping fiange- Hb sized and shaped to seat and grip the exterior surface of container open end [20 under, that is, inwardly of said head lZd. And spaced from said band portion I la but joining therewith through an integrally formed foldable hinge interconnect-ion llc there is provided a capping portion lid of a size and shape to extend over the container open end l2c as shown in Figs. 1 to 4:.

Said capping portion lid, as here shown, has a contour substantially like annular band portion I to but having a somewhat larger spread to provide an encircling peripheral sealing edge border Us. An integral collar or ring He may be provided to outstand from depressed surface it) of said. capping portion lid. and convex surface I I g of said capping portion l I at opposite said surface I l 1 may have projecting therefrom spaced apart, reinforcing ribs Hh which extend there across from said hinge interconnection lie to anintegral finger engaging lip, H 7 terminating the.

free end of capping portion I Id. One or more spaced depressions Ilk may be provided in capping portion lId asfor example, in the mid section thereof between reinforcing ribs Ilh, thin walls Ilm of said depression IIIc being puncturable to form through-passage for communicating the interior of container I2 with the surrounding atmosphere, as is clear from Figs. 3 to 5.

For further stiffening capping portion l Id additional reinforcing means such as rib IIn spaced from and extending in the same direction as said rib it may be provided if desired to brace said capping portion II d against bending stress and strains when finger pressure is applied to lip H1 on opening or on closing said capping portion lld from a seated position shown in Fig. 3 in the manner hereinafter described.

After constructing or providing a suitable container I2, and a cap-stopper closure II as above described and shown in Figs. 1 to 6, the utility of the invention for use as a packaging'device Ill of the character described will be apparent.

Container I2 may be fitted with said annular band portion flange Ila so that the latter is clampingly seated on exterior surface of container I2 against rim bead I 2d, as shown in Fig. 5, in which position capping portion II 01 is in normally molded stretched out open position. The contents, namely, toothbrush B can then be readily inserted in the container I2 and by finger gripping lip Ila, capping portion Ild may be folded over container open end I20 by bending hinge interconnection I la transversely the length thereof at bight Hp, as shown in Figs. 1 and 3, and rim edge border of collar Ile forced in a releasably capping position against the interior surface at said container open end I20, said collar Ile being shaped and sized to snugly seat in said open end l2c and said edge border Hs forming a peripheral sealing joint as shown in Figs. 1 to 3.

Packaging device It! when sealed closed may be readily opened by simply grasping container I2 in hand and exerting a lifting force with respect thereto on finger engaging lip H7. Once the sealing joint formed by edge border Us is broken and the collar I la unseated from container open end I20 sealing portion Ild will spring into stretched open position shown in Fig. 5. g

If it is desired to ventilate the interior of container I2 of package device I fitted with capstopper closure II in effective position, thin wall depression I Im may be pierced or out to provide through-passage communicating with the atmo phere as is clear from Figs. 1 to 4.

It will thus be seen that there is provided a packaging device and cap-stopper closure of the character described whereby the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or. shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
